Found this thread and followed the instructions towards the bottom - https://github.com/QubesOS/qubes-issues/issues/4610
Blacklisting Nouveau results in the laptop display working off of the Intel GPU only, no monitor and the Nvidia listed in lscpi -v with no driver.
Unless I've misunderstood, the above thread suggests to me that the 5.6.x kernel 'includes Nvidia' so I'm interpreting that as it has native Nvidia support. I've also done a Fedora update.
If anyone can give me any pointers please it would be appreciated.
